If a driver is going straight with a green light and another driver is turning right the driver going straight is getting over at the same time the driver is going right and they collide who's fault is it?

Assuming you was in the left lane merging into the right lane they were making a right turn from... you would be at fault... its called failure to yield. They were in the lane first... they have the right of way.

And in fact you are not supposed to be changing lanes while in an intersection either.

I was past the intersection

You are at fault... the car that was already in that lane had the right of way... doesn't matter if they started to turn then stopped. It's your responsibility to assure the lane is free and clear of anything (car, truck motorcycle, bicycle or pedestrian) before you turn into it.

I was the one going straight! He was turning rt

Who was in the left lane and who was in the right lane? Or did you hit him in the back?

If he was turning right, how did he hit your right side... who crossed the white line dividing the lanes?

It is hard to envision how if you were moving into the right lane and another vehicle was already there (whether that car was turning, about to turn or even had decided not to turn) how it could be the other driver's fault.
Sounds like the car didn't turn right after giving you the impression that they were going to turn right based on the other car's left front colliding with your passenger side. Unless there are some other unusual circumstances that you haven't mentioned, it sounds like you failed to yield right of way as smoothie has indicated.

Seems like possible dual fault. Driver going staight did moved over a lane inside a intercestion. ( at least in the couple states I was a police officer in, that is illegal) Next he did a lane change into a lane that was not clear.

The other car did a right hand turn with failure to yield.

Based on what you said, and depending on how far past the intersection it happened, both are at fault.

OP has been pretty unspecific, but would this type of damage occur if the other driver was turning onto the street that he was travelling on?
I think you need to clarify the scenario.
As it is, it just doesn't really make sense.
